Definitions
- the present invention relates to an auto switching swimming pool/spa heater system wherein only a single heater unit need be used and switching on of the spa automatically results in shutting down the pool pump.
- the system of the present invention is specifically adapted to provide for the efficient use and effective and facilitated switch over from spa use to swimming pool use utilizing solely a spa switch.
- the present invention is directed towards an auto switching swimming pool/spa heater system to be utilized with a pool and a spa combination.
- the pool and the spa each being of the type including a drain therein and being disposed with relation to one another such that excess water in the spa overflows into the pool.
- the auto switching swimming pool/spa heater system of the present invention includes a single heater unit.
- the single heater unit includes a spa water intake, a pool water intake, a water outlet, a coiled heat exchange conduit, and an internal pool/spa flow control apparatus.
- the coiled heating exchange conduit is disposed within the heater unit so as to facilitate the passage of water through the heater unit, the water being heated during its passage therethrough.
- the system includes a pool pump and a pool drainage conduit.
- the pool drainage conduit is disposed between the pool pump and the pool drain such that the pool pump will draw water from the pool through the pool drain and the pool drainage conduit into the pool pump.
- Extending from the pool pump and disposed in fluid communication therewith is a pool pump outlet conduit.
- the pool pump outlet conduit directs water exiting the pool pump to a pool/heater junction.
- the pool/heater junction which is connected to the pool pump outlet conduit at its pump inlet splits into a pool outlet and a heater outlet.
- the pool/heater junction includes a flow control valve adapted to regulate the proportion of water exiting the pool/heater junction through the pool outlet and the heater outlet.
- a pool inlet conduit is connected to the pool outlet of the pool/heater junction and thereby directs water exiting the pool/heater junction back into the pool.
- a heater inlet conduit is connected to the heater outlet of the pool/heater junction. The heater outlet is adapted to direct the pool water into the pool water intake of the heater unit.
- a spa pump Utilizing a spa drainage conduit connected in fluid flow communication between the spa pump and the spa drain, the spa pump draws water from the spa through the drain and the spa drainage conduit.
- a spa pump outlet conduit connected to the spa pump, directs water exiting the spa pump to the spa water intake of the heater unit.
- a flow switch Further included within the spa pump outlet conduit is a flow switch. The flow switch is adapted to shut off the pool pump upon the passage of water through the spa pump outlet conduits.
- both the spa water intake and the pool water intake include a one-way valve therein such that water can flow only into the heater unit through the respective intakes.
- the spa water intake and pool water intake direct water into the internal pool/spa flow control apparatus within the heater unit.
- the flow control apparatus includes a heater flow junction and a bypass conduit.
- the heater flow junction includes a single water inlet to receive water from the spa water intake and the pool water intake, and includes two outlets, namely, a bypass outlet and a heat exchange outlet.
- the bypass outlet directs water into the bypass conduit and the heat exchange outlet directs water into the heat exchange conduit for subsequent heating of the water.
- Disposed within the bypass conduit is a spring loaded flow regulator valve.
- the water flow is directed out solely through the heat exchange outlet.
- Water flow pressure can, however, build up during use as no water can exit through the one-way valves within the spa water intake and the pool water intake.
- the spring loaded flow regulator valve within the bypass conduit will open enabling some of the water to bypass the heat exchange conduit and be directed immediately to the water outlet.
- Water exiting both the bypass conduit and the heat exchange conduit pass through the water outlet of the heater unit so as to exit the heater unit.
- a spa water return conduit Connected to the water outlet of the heater unit is a spa water return conduit. The spa water return conduit directs all water exiting the heater to the spa thereby filling the spa.
- the spa pump has been turned on so as to be the only pump operating, water merely circulates through the spa maintaining its substantially constant level. If, however, the pool pump is on, the water drawn from the swimming pool directly is sent into the spa upon exiting the heater, thereby resulting in the water level in the spa to increase until the heated spa water flows out of the spa and into the pool.
- Still another object of the present invention is to provide a pool/spa heater system which can be easily switched from pool use to spa use merely by turning on the spa pump.
- a further object of the present invention is to provide a pool/spa heater system which will not unnecessarily allow the pool pump to function during spa use.
- Yet another object of the present invention is to provide a pool/spa heater system which does not require frequent and complicated valve adjustments during pool to spa conversion and use unless expressly desired.
- FIG. 1 is a schematic of the pool/spa heater system during pool only heating use.
- FIG. 2 is a detailed schematic of the pool/spa heater system illustrating spa only heater use.
- FIG. 3 is a detailed schematic of the pool/spa heater system illustrating combination pool and spa heater use.
- FIG. 4 is a detailed schematic of an alternative embodiment of the pool/spa heater system.
- the heater system 10 is adapted to be used with a swimming pool 100 and spa 102 combination.
- the combination is of the type wherein the spa 102 overhangs the pool 100 at a lip 104, the lip 104 being disposed to enable excess water within the spa 102 to overflow into the pool 100.
- the pool 100 and spa 102 each include a respective drain 101 and 103 wherethrough a majority of the water exiting the pool passes.
- Most swimming pools 100 or spas 102 include such main drains 101 and 103 in the bottom surface thereof to facilitate the extraction of the water for filtration and heating.
- the heater system 10 includes a single heater unit 20 to be utilized to heat both the pool 100 and spa 102, thereby maximizing the efficiency of the system.
- the heater system 10 includes an independent pool pump 40.
- the pool pump 40 is adapted to draw water from the swimming pool 100 through the drain 101 of the pool 100.
- a pool drainage conduit 42 is disposed between the pool drain 101 and the pool pump 40.
- the pool pump 40 is a standard-type pool pump which draws water in from the pool 100 and pushes it out for filtration or heating before returning to the pool 100.
- Extending from the pool pump 40 is a pool pump outlet conduit 44.
- a pool filter 80 is included with the pool pump outlet conduit 44 such that water exiting the pool pump 40 is forced through the filter 80.
- the pool pump outlet conduit 44 connects the pool pump 40 with a pool/heater junction 45.
- the pool/heater junction 45 specifically includes a single pump inlet 46 and two outlets 47 and 48. More particularly, the outlets include a pool outlet 48 and a heater outlet 47. Further included as part of the pool/heater junction 45, and positionable either directly at the pool outlet 48 or slightly down flow therefrom, is a flow control valve 49.
- the flow control valve 49 which may be manually adjusted by a user as necessary is adapted to control the proportion of water which exits the pool/heater junction 45 through the pool outlet 48 as opposed to the heater outlet 47. This flow control valve 49 is adapted to be set by a user and left at a desired setting for extended periods of time without further adjustment.
- the valve 49 can be set at either all heater outlet 47 flow or all pool outlet 48 flow, the primary difference being that water passing through the heater outlet 47 will be able to be heated by the heater unit 20 before returning to the pool 100. Preferably, however, the valve 49 will be set somewhere between the two extremes, depending upon the desired heating rate or system requirements of the user.
- a pool inlet conduit 50 Extending from the pool outlet 48 of the pool/heater junction 45 is a pool inlet conduit 50.
- the pool inlet conduit 50 directs water exiting the pool/heater junction 45 through the pool outlet 48 back into the swimming pool 100.
- Connected to the heater outlet 47 of the pool/heater junction 45 is a heater inlet conduit 51.
- the heater inlet conduit 51 directs water exiting the pool/heater junction 45 through the heater outlet 47 into the heater unit 20. In order to direct water flow into the heater unit 20, the heater inlet conduit is connected to a pool water intake 22 of the heater unit 20.
- a standard spa pump 60 is included.
- the spa pump 60 is adapted to draw water from the spa 102 through the spa drain 103.
- a spa drainage conduit 62 Connected between the spa pump 60 and the spa drain 103 is a spa drainage conduit 62. Water enters the spa pump 60 through the spa drainage conduit 62 and exits the spa pump 60 through a spa pump outlet conduit 64.
- the spa pump outlet conduit 64 includes a filter 81, as illustrated in FIG. 4, adapted to filter the water exiting the spa pump 60.
- the spa pump outlet conduit 64 is primarily adapted to direct the water from the spa pump 60 to the heater unit 20. More particularly, the spa pump outlet conduit 64 is connected with a spa water intake 21 of the heater unit 20 wherethrough spa water enters the heater unit 20.
- the flow switch 70 is disposed within the spa pump outlet conduit 64 so as to detect, and be triggered by water flow through the spa pump outlet conduit 64. Accordingly, the flow switch 70 is engaged when the spa pump 60 is on, drawing water from the spa 102 and passing it through the spa pump outlet conduit 64 to the heater unit 20. Similarly, if the spa pump 60 is disengaged resulting in the water flow ceasing through the spa pump outlet conduit 64, the flow switch 70 is disengaged.
- the flow switch 70 is connected with the pool pump 40. More particularly, the flow switch 70 is specifically adapted to turn off the pool pump 40 when it is engaged, and to allow the pool pump 40 to turn on when the flow switch 70 is disengaged.
- the flow switch 70 is included to enable a user to shut down the pool pump 40 merely by turning on the spa pump 60.
- the shutting down of the pool pump 40 is desirable because if a user wants to use only the spa 102, there is no need for the pool pump 40 to be running and for pool water to be heated.
- the flow switch 70 functions so that the pool pump 40 will be off when the flow switch 70 is engaged, but when the flow switch 70 is disengaged, it does not function to automatically turn on the pool pump 40. When disengaged, the flow switch 70 functions to allow the pool pump 40 to turn on. Pool pump 40 functioning is dictated by the specific needs of the user or by the normal pool pump 40 functioning cycles as set by the user.
- the heater system 10 includes a timer 71.
- the timer 71 is specifically adapted to be set by a user to indicate when the pool pump 40 is to turn on and when the pool pump 40 to turn off.
- the timer 71 is particularly effective to enable to the pool 100 to be filtered and heated as necessary without requiring constant inefficient working of the pool pump 40 and heater unit 20 when the pool is not in use or when additional heating or filtration of the pool 100 is not necessary.
- the pool pump 40 will turn off even if the pool pump 40 was set to be in its operation cycle by the timer 71, or if the pool pump 40 was manually turned on by a user.
- the flow switch 70 is disengaged, however, the pool pump 40 will only turn on if manually turned on by a user, if so dictated by the timer 71, or if turned on by some other control means connected to the pump 40.
- An additional feature included as part of an alternative embodiment is a flow switch bypass.
- the flow switch bypass is included as part of the flow switch 70 and is adapted to enable a user to selectively disengage the flow switch 70.
- the flow switch 70 can be disengaged such that during those circumstances when a user desires both the pool pump 40 and the spa pump 60 to be functioning, flow through the spa pump outlet conduit 64 will not turn off the pool pump 40.
- the timer 71 may be adapted to automatically or selectively engage the flow switch bypass while the pool pump 40 is set to be turned on by the timer 71, thereby enabling regular pool filtration and heating cycles to continue normally.
- the heater unit 20 of the heater system 10 includes primarily the spa water intake 21, the pool water intake 22, a water outlet 23, and a coiled heat exchange conduit 25 disposed therein.
- the coiled heat exchange conduit 25 is included within the heater unit so as to maximize the amount of time during which water passing through the heater unit 20 is exposed to heat.
- the heater unit 20 is preferably a conventional style swimming pool heater unit.
- Further included within the heater unit 20 is an internal pool/spa flow control apparatus 30.
- the pool/spa flow control apparatus 30 includes a heater flow junction 31 and a bypass conduit 35. More particularly, the heater flow junction 31 includes a single water inlet 32, a bypass outlet 34, and a heat exchange outlet 33.
- the water inlet 32 of the heater flow junction 31 is adapted to receive water entering the heater 20 through both the spa water intake 21 and the pool water intake 22. Included at the spa water intake 21 and the pool water intake 22 are a pair of one-way valves 27 and 28, respectively.
- the one-way valves 27 and 28 are specifically adapted to enable the water to enter the heater flow junction 31 through the water inlet 32, but only allow water to exit the heater flow junction 31 through either the heat exchange outlet 33 or the bypass outlet 34.
- the heat exchange outlet 33 is connected to the heat exchange conduit 25 within the heater unit 20 such that water exiting the heater flow junction 31 through the heat exchange outlet 33 will be subsequently heated before return to the pool 100 or spa 102.
- water exiting the heater flow junction 31 may enter the bypass conduit 35 through the bypass outlet 34.
- the bypass conduit 35 includes therein a spring loaded flow regulator valve 36.
- the spring loaded flow regulator valve 36 is specifically adapted to enable water to pass therethrough only upon sufficient water flow pressure build up at the flow regulator valve 36.
- all water will preferably pass through the heat exchange conduit 25 for heating. In some circumstances, however, such as when water is entering the heater flow junction from both the spa water intake 21 and the pool water intake 22, water can back up at the heater flow junction 31. Because the spa water intake 21 and the pool water intake 22 each include a one-way valve 27 and 28 therein, water can only easily exit the heater flow junction 31 through the heat exchange outlet 33.
- the bypass conduit 35 is included. Accordingly, through the use of the spring loaded flow regulator valve 36, only when there is a specific need, due to increased water flow pressure build up at the heater flow junction 31, will the flow regulator valve 36 allow water to bypass being heated. Both the bypass conduit 35 and the heat exchange conduit 25 direct water out of the heater unit 20 through the water outlet 23. Connected to this water outlet 23 is a spa water return conduit 38. The spa water return conduit 38 directs all water exiting the heater unit 20 into the spa 102. As a result, even heated pool water whose final destination is the swimming pool 100 will enter the spa 102 initially before entering the pool 100.
- FIGS. 1-3 illustrated are the various operation combinations of the heater system 10.
- water exits the pool 100, passes through the pool pump 40, exits the pool pump 40, and is directed partially back into the pool 100 and partially to the heater unit 20 depending on the setting of the flow control valve 49.
- water goes into the spa 102 and not back into the pool 100.
- the spa 102 becomes more and more filled.
- the spa 102 becomes sufficiently filled such that the water level rises above the lip 104 resulting in an overflow of heated water into the swimming pool 100, thereby heating the swimming pool 100.
- FIG. 2 when water is drawn directly from the spa 102, the pool pump 40 is turned off and the water is directed through the heater unit 20 and back into the spa 102. Because the water is drawn from the spa 102 and replaced to the spa 102, the water level of the spa will never increase so as to result in an overflow to the pool 100.
- a primary benefit of the use of the heater system 10 of the present invention involves the ability to shut down the pool pump 40 simply by turning on the spa pump 60 so that the pool pump 40 is not unnecessarily operating.
- the heater system 10 may include in an alternative embodiment remote switching means 85.
- the remote switching means 85 may be in the form of an air switch, a wireless remote, or a wired remote, as well as any other type of remote which will enable a user to turn on the spa pump 60 from a remote location, preferably the spa 100 itself.
- the various conduits utilized as part of the present invention are preferably made of a standard PVC material, but any other similar material may be utilized.
